My experience with silent migraines is that I pass through the other three phases of migraine, but my body skips the pain step.
My symptoms started two years ago. I started with shoulder pain, which progressed toy entire arm feeling pins and needles. The pins and needles moved (over time) to all limbs and my face. They have improved now, but still come on occasion. Other symptoms include dizziness, feeling like I can't keep my eyes open, lack of balance, Total exhaustion, dropping things, brain fog, and nausea.
I am thankful to be learning things that help. I take CoQ10 and magnesium supplements. I also made major changes to my diet, exercise, drink tons of water, drink less caffeine and get lots more sleep than I used to. Another huge help has been a very recent addition: tinted glasses. I put them on when I'm feeling a flareup coming on, and they help a lot. I just got started with an upper cervical chiropractor as well and feel very hopeful about that.
I truly appreciate this group. I'm learning so much from all of you. Thank you for helping feel like others understand!

I sometimes have silent migraines, and have never had it show up on an MRI

"Migraines" cannot be "seen" w any imaging protocols. Plaques, brain abnormalities, vessel abnormalities, etc are the only thing that can be imaged.

I experience similar symptoms with not headache as well. I also have VERY prolonged predrome and postdrome. How long do your bouts usually last? I take magesium but not COQ10. Has that helped?

Thank you so much, everyone. I truly appreciate your responses.
